Presidential Election Winner 2028

Platform comparison

Market context

The 2028 US presidential election, set for 7 November 2028, will determine who holds the office for the term beginning in 2029. Current crowd-implied probability sits at 20% YES for a specific candidate, reflecting a market that views the outcome as an underdog scenario rather than a favourite. Historically, early-cycle probabilities in non-incumbent years often misprice value; for instance, the 2016 and 2020 cycles saw initial odds drift significantly before the nomination process clarified the field. The complex "winnowing" of candidates through primaries and conventions, as detailed by the Overseas Vote Foundation, means that early 20% odds frequently offer contrarian value spots once the party conventions in 2028 narrow the field to serious contenders.

Traders must monitor the nomination calendar, specifically the Iowa and New Hampshire caucuses that traditionally kick off the Republican and Democratic processes, alongside the delegate thresholds required at the 2028 national conventions. Recent commentary from The Hill suggests that a landslide victory may be necessary to renew democratic confidence, implying that a candidate with a 20% implied chance could be undervalued if they possess a broad electoral map advantage. The 270toWin electoral college map indicates that securing 270 votes remains the critical dependency, making state-level polling shifts and campaign finance data from the FEC the primary catalysts to watch. As Democrats begin defining their identity for 2028, the market’s consensus may be too bearish on candidates who can consolidate the base, offering a value spot for those who can navigate the complex nomination rules.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
